Memcached mcperf

This is a test of twmperf/mcperf with memcached, a distributed memory object caching system.

This pts/mcperf test profile for memcached is deprecated. Instead use the pts/memcached test profile for better evaluating the Memcached CPU/system performance with its memtier_benchmark setup.

To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark mcperf.

Use with caution this test profile is currently marked Deprecated.

Revision History

pts/mcperf-1.4.1   [View Source]   Fri, 19 Aug 2022 14:44:33 GMT
Deprecate pts/mcperf as the pts/memcached test profile works better for stressing system/CPU benchmark.

pts/mcperf-1.4.0   [View Source]   Thu, 21 Jan 2021 10:44:16 GMT
Update against latest upstream for build fix.

pts/mcperf-1.3.0   [View Source]   Mon, 09 Mar 2020 14:03:32 GMT
Update against memcached 1.6.0 upstream.

pts/mcperf-1.2.0   [View Source]   Sat, 07 Mar 2020 13:57:26 GMT
Update against latest memcached upstream, fix root, allow option for selecting connection count.

pts/mcperf-1.1.1   [View Source]   Wed, 03 Oct 2018 19:14:56 GMT
Add patch to allow memcached benchmark to work as root.

pts/mcperf-1.1.0   [View Source]   Wed, 03 Oct 2018 08:28:45 GMT
Update against memcached 1.5.10, which also fixes the older test failing to build on newer Linux distributions/compilers (GCC8).
